The invention relates to the production of PMI foams, more particularly to their formulating ingredients, which lead to particular facility in adjusting the density at given foaming temperature.

Polyfunctional alcohols as cross-linkers in PMI foams

The invention relates to compounds for producing polymethacrylimide foam materials (PMI foams) with particularly good mechanical properties, in particular with a particularly advantageous elongation at tear. The invention further relates to methods for producing, processing, and using said foam materials. In particular, the invention relates to novel materials, the propensity of which to form tears is clearly reduced in comparison to the prior art. This is tantamount to an elongation at tear that is higher in comparison to the prior art.

PMI foams with improved mechanical properties, in particular with increased elongation at tear

The invention relates to compositions for producing polymethacrylimide foams having reduced pore size. The inventive method allows production of a microporous foam with an especially homogeneous pore size distribution without having to use insoluble nucleation agents.

Thermostable microporous polymethacrylimide foams

By using a high molecular weight syrup phase comprising PMMA or PMMI, it is possible to distribute fillers in the polymerization batch so that the distribution of the fillers remains homogeneous during the polymerization. A homogeneous foam results.
